My friends and I enjoyed our stay in BKK all thanks to Kay and his place.
We arrived quite late (early?) at around 1am in the airport so we were nervous if we would be able to go to the place with no problem. Kay gave us the address in Thai to show to the taxi driver so we thought there'll be no problem. Unfortunately the taxi driver we got didn't know the place so we spent 15 minutes or so trying to explain it to him which was hard bcs he couldn't understand English at all. When we figured it out, we went to the place. It takes around 20 to 30 mins from the airport if you use the highway. When we got to the area however, the taxi driver still couldn't figure out where the place was so he drove around which obviously added to the rate (lol). But when we finally saw the sign "The Base" we decided to just get off there even if Kay specifically told us that we should ask the driver to take us in bcs it's The Base Park East which is inside. Unfortunately we rly can't communicate it to the driver so we decided to walk instead (took us 10 minutes or so). So my suggestion is to print out not just the address but an area map in Thai, how to say "Please go inside The Base bcs Park East is inside" in Thai and download Waze.
The facilities inside are complete– we got stable internet connection, towels and toiletries, cooking wares (we cooked dinner every night), tv (but we couldn't get it to work so maybe you should bring a flash drive with movies), and a very comfortable bed with a perfect view. It's quite small but definitely homey and perfect for a vacation. Don't miss going for a night swim too bcs the pool has a very nice view. There is a shuttle that takes you to the gate and BTS is walking distance (around 15 minutes). Tip, the 7-11 near the BTS On Nut is the best and the money changer near the BTS (not Super Rich) has the best exchange rate.
Place is super convenient tho quite far from the heart of BKK. You can go anywhere using the BTS anyway and taxi is not thaaat expensive (we used Grab all the way). There's a nice market where you can buy fresh food and there's a mini night market besides Big C.
Kay is always available and easily reachable when you have a question. Just a small warning, the condo apparently has a "no tourist" rule so try not to look like such a tourist when you go there. Nobody asked us but it still made us nervous.
Bottom line, the place is great and perfect for the value. We really enjoyed our stay. Will def go back here for my next BKK trip. I truly recommend it to everyone.
